# s-gst-game: tit-for-tat and the emergence of morality

<< Ultimately, the results showed that the best strategy was 'tit for tat' – which means that a player starts out cooperating on the first move, and then does whatever it's opponent does >>

<< it's interesting that it emerged – it self-organised – into this state of being that the Old Testament morality ended up winning in this environment >>

<< So in fact what was found in later studies, when they examined prisoner's dilemma in environments where errors occurred with a certain frequency, is that the population tended to evolve to more generous, more like New Testament strategies that will 'turn the other cheek' >>

<< If natural selection leads to morality, that's pretty interesting. And that came from maths! >>.  Steven  Strogatz.

FonT: <<  and then does whatever it's opponent does >> ... approccio senz'altro utile all'interno di scenari di simulazione; in contesti reali un approccio creativo, esplorativo, perturbativo, e per mia opinione anche funzionale, al problema di  decidere sul comportamento cooperativo al successivo "run" e' quello di affidarsi all'esito del lancio di moneta, ovviamente dopo un giudizio (formato da componenti di natura analitica ma anche soggettiva) circa il contesto che ha fatto intravedere la necessita' - per l'attore cooperativo - di una biforcazione, di operare una scelta.

Percio' "tit-for-tat generoso quasistocastico", tutte le volte che un gambler decide di iniziare/ sostenere un gioco "al buio", anche quando sa, oppure sospetta, che il gioco e' "a priori" fondamentalmente truccato, vale a dire deviante dai due vincoli del gioco legale, naturale [1,2,3]

Nelle componenti  "eye for an eye" vs "turn the other cheek" o, se si vuole piu' in generale, nei livelli di "risveglio" in senso buddista degli attori partecipanti tit-for-tat, dipende, anche a breve/ medio termine, la velocita' evolutiva degli esiti del gioco, esiti che riverberano in ambito sociale, anche all'interno di contesti "altri".

# game: in a iterated prisoner's dilemma scenario forgiveness turns out to be an adaptation

<< Prisoner’s dilemma is used to represent a range of real life phenomena such as economics, commerce, nature and wildlife. >>

<< Researchers working on iterated prisoner's dilemma (IPD) with limited memory inspected the outcome of different forgetting strategies in homogeneous environment, within which all agents adopt the same forgetting strategy at a time. In this work, with the intention to represent real life more realistically, (AA) improve existing forgetting strategies, offer new ones, and conduct experiments in heterogeneous environment that contains mixed agents and compare the results with previous research as well as homogeneous environment >>

<< in a more realistic environment consisting of all types of agents, in terms of both cooperation probabilities and forgetting strategies, agents who forget defectors consistently outperform other forgetting strategies for all memory ratio values. Moreover, the best performing defectors are also the ones that forget other defectors. In other words, agents who “forgive” defectors are the best performers. Hence, forgiveness is an adaptation. >>

FonT: as mentioned elsewhere in this blog, from my point of view, if well modulated, the two paired strategies "Stochastic Tit-For-Tat" and "Parrondo" are deadly, regardless of the aims of the objectives (cooperative purposes, parasitism, resurfacing of hypothetical clusters of failed entities, ... )

# game: apropos of Parrondo's paradox, winning with losses driven by reputation and reciprocity

AA << investigate two such social behaviors, reputation and reciprocity, and their role in explaining Darwin’s survival of the fittest, examining how these fundamental principles govern individual interactions and shape broader social dynamics. >>

<< Current theories hint at two main facets of social interaction, reputation and reciprocity, as potential drivers behind this cooperative evolution. Reputation revolves around building and sustaining trust, social worth, and overall community standing. Conversely, reciprocity governs the mutual exchange of actions or benefits, influencing our choices. >>

<< One intriguing concept explored in this domain is Parrondo’s paradox: combining or switching between two losing strategies might surprisingly achieve a winning outcome. The role of Parrondo’s paradox in complex systems has sparked key research into chaotic many-body, quantum, and algorithmic network applications, where combining elements yields opposing beneficial results. Similarly, social physicists aim to uncover hidden mechanisms that govern societal phenomena by integrating the paradox’s counterintuitive principles. >>️

<< The game-theoretic Parrondo’s paradox emerges through multiple iterations of these interactions (..) A naive observation might conclude that in either scheme the chance of individuals losing to the environment is higher than gaining from the environment. For the reputation scheme, one is rewarded with a singular capital from the environment but is punished with two. Similarly, the reciprocity scheme only allows for the redistribution of capital or loss of capital. In reality, diverse schemes can be adopted by different individuals. Thus, (AA) suggest two forms of switching: (1) stochastic switching, where the individual randomly selects one of two schemes to employ with equal probability, and (2) rule-based switching, where the individual only selects the reputation scheme if it passes the reputation threshold ρ; otherwise, it employs the reciprocity scheme. >>

AA << also performed simulations on other network topologies (..) Parrondo’s paradox is strongly observed in small-world networks, weakly in the Erdős-Rényi network, and absent in scale-free networks. >>

To conclude, some of these observations << underscore the profound capability of rule-based switching mechanisms inherent in Parrondo’s paradox to emulate and forecast key aspects of real-world social phenomena. Such insights are invaluable for developing sophisticated models and strategies in various fields, ranging from social sciences to policy making, where accurate predictions of social behavior and dynamics are crucial. >>

# game: aperiodic Parrondo (behavior based on the binary Fibonacci, Thue–Morse and Rudin–Shapiro sequences); persistence and heterogeneity effects.

AA << study the effectiveness of employing archetypal aperiodic sequencing -- namely Fibonacci, Thue-Morse, and Rudin-Saphiro -- on the Parrondian effect. From a capital gain perspective, (their) results show that these series do yield a Parrondo's Paradox with the Thue-Morse based strategy outperforming not only the other two aperiodic strategies but benchmark Parrondian games with random and periodical (AABBAABB…) switching as well. The least performing of the three aperiodic strategies is the Rudin-Shapiro. >>

AA << analyze the cross-correlation between the capital generated by the switching protocols and that of the isolated losing games. This analysis reveals that a pronounced anti-correlation (below -0.95) with both isolated games is typically required to achieve a robust manifestation of Parrondo's effect. >>

About << the influence of the sequencing on the capital using the lacunarity and persistence measures (AA) observe that the switching protocols tend to become less performing in terms of the capital as one increases the persistence and thus approaches the features of an isolated losing game. >>

Respect to << lacunarity, a property related to heterogeneity, (AA) notice that for small persistence the performance increases with the lacunarity with a maximum (..). In respect of this, (AA) work shows that  the optimisation of a switching protocol is strongly dependent on a fine tune between persistence and heterogeneity. >>

# gst: transitions by coupled instabilities

AA << present an experimental study of quasiperiodic transitions between a highly ordered square-lattice pattern and a disordered, defect-riddled state, in a circular Faraday system. (They)  show that the transition is driven initially by a long-wave amplitude modulation instability, which excites the oscillatory transition phase instability, leading to the formation of dislocations in the Faraday lattice. The appearance of dislocations dampens amplitude modulations, which prevents further defects from being created and allows the system to relax back to its ordered state. The process then repeats itself in a quasiperiodic manner. >>
